[android-developers] Re: Update delete a directory and how to prevent this from happening?
I did use getExteranlStorageDirectory() method but i realize Android always mount it to /sdcard I am starting to think why not hardcode. I guess Google team will not change it (maybe the source /mnt/sdacrd but not the mount path), then again I guess it is a good practise and I will change it. :) thank for the advice.

That is not a good idea, though I think you are confusing two methods. Environment has a getExteranlStorageDirectory() method, which points to the root of the external storage (e.g., /mnt/sdcard). I was referring to the getExternalFilesDir() method on Context, new to Android 2.2: http://developer.android.com/reference/android/content/Context.html#getExternalFilesDir(java.lang.String) > You mean a > bug if I had getExternalFilesDir() in my code and it will delete the > directory each time I call it? No, but a bug in getExternalFilesDir() will cause that directory to be deleted on an upgrade, which I thought was your problem. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy Android Development Wiki: http://wiki.andmob.org -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Thanks Mark, I have your books and use it here and there. I didnt use getExternalFilesDir(), I hardcore it directly. You mean a bug if I had getExternalFilesDir() in my code and it will delete the directory each time I call it?

If you're using the new getExternalFilesDir(), what you are experiencing is a bug.

Yep, sounds logical and that is what I understood too. I have the directory in the SD and I believe it should not be deleted.
